Abstract excerpt
CD19 is among the most relevant targets in cancer immunotherapy. However, its extracellular domain (ECD) is prone to aggregation and misfolding, representing a major obstacle for the development and analysis of CD19-targeted therapeutics. Here, we engineered stabilized CD19-ECD (termed SuperFolder) variants, which also showed improved expression rates and, in contrast to the wild type protein, they could be...
